Also ... As far as I know, “software-defined radio” is not a fully standardized term that has one official meaning. So the first thing I need to do is establish what exactly I mean when I say “software-defined radio.” Actually, I’ll start by mentioning two things that I don’t mean:

    Principles of Communication - FM Radio - Tutorialspoint

    Principles of Communication - FM Radio - Frequency division multiplexing is used in radio and television receivers. The main use of FM is for radio communications. Let us take a look at the structure o Antenna Theory - Near and Far Fields - After the antenna parameters discussed in the previous chapter, another important topic of consideration is the near field and the far field regions of the ante Abstract. The concept of Cognitive Radio (CR) appeared as a new paradigm in 1999 as an extension of Software Defined Radio (SDR). It describes the situation where intelligent radio devices and associated network entities communicate in such a manner that they are able to adjust their operating parameters according to the needs of the user/network, and learning from experience at the same time.
